is there any good way to quiet them down? my truck hasn't been ridden hard, i'm just wondering why i'm getting so much noise. it started right after my last oil change. i flushed the motor with gunk motor flush and filled it up with 6 quarts of 10w-30 valvoline syn-blend high mileage. my dad likes to tease me and says that the engine sludge was keeping the lifter quiet in the first place...ugh
